i am getting an error when trying to bid a radgrid to a LLBLGenProDtatsource with an entitiy collection -- the error appears to be related to the type of one of the entity fields.

Background: originally the column in the SQL database was of type INT, and was being converted to type System.Boolean using the type converter when assigned to the field of the Entity in question.

I modified the table to change the type of that column to BIT and refreshed the catalog in LLBL generator (v2.5, Dec 5 2007) to change the field to the relfect the new type (System.Boolean with no need for type conversion.)

After the change, i got the following runtime error:

Conversion from a value of type 'System.Boolean' to System.Boolean isn't supported 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
